ABSTRACT:
Apparatus and method are disclosed for handling a flexible disk for testing. The apparatus includes guide rails for initially positioning a disk for test. The apparatus also includes a variable speed motor for rotating the disk at a preselected rotation speed. The disk is rotated by clamping the disk betwen a motor driven rotating spindle and a retractable collet. The collet passes through an aperture in the disk to center and position the disk. Testing is accomplished by a test head assembly which is moved by a voice coil actuator. Positioning of the test head assembly is controlled by a light detector and ground glass scale coupled to the actuator and to the test head assembly.
